Abstract: U1.00004 : Glassiness in RNA folding

We study secondary structures of random RNA molecules by means of
a renormalized field theory based on an expansion in the sequence
disorder. We show that there is a continuous phase transition
from a molten phase at higher temperatures to a low-temperature
glass phase. Based on an exact inequality, we argue that RNA
conformations in the glass phase are similar to those at the
transition.
